Conservatory cleaning cost: Prices by size, service & location

Conservatories have long been a beloved feature of traditional British homes. These days, there are loads of modern conservatory ideas, from cosy reading nooks to home offices and dining spaces. But no matter how you use yours, one thing’s certain: keeping it clean is no small task.

Since conservatories are mostly made of glass, regular cleaning is a must if you want to keep those windows streak-free and light pouring in. On average, conservatory cleaning costs around £425 in the UK. But what actually affects that price? Could your final bill be lower? Let’s break it down in this guide.

Conservatory cleaning price list

Where you live can make a big difference to conservatory cleaning costs. Your location often dictates how many local cleaners are available and what rates they charge. Areas with higher demand or fewer specialists may see steeper prices. Below, you’ll find the average conservatory cleaning cost by location to help you set a realistic budget.

Of course, the biggest factor in your final bill is the type of cleaning you need. Whether you’re after a basic exterior wash, a full interior deep clean, or both. Check out the breakdown below to see what each cleaning option might cost.

Factors affecting conservatory cleaning prices

Wondering why conservatory cleaning quotes can vary so much? It all comes down to a few key factors, including the size of your space, where you live, the type of cleaning you need, and how tricky the job is.

Conservatory size

Size is one of the biggest factors when it comes to conservatory cleaning prices. The more glass panels and surface area, the more time and effort a professional cleaner will need to get the job done right. Here’s what you can expect based on conservatory size:

A small lean-to conservatory might only cost £30 to £50 for basic cleaning, while medium-sized spaces (around 12–20 sqm) can range from £50 to £80, depending on the service. Larger builds like Victorian or Edwardian-style orangeries and conservatories (often 35 sqm or more) can cost between £80 and £150, especially if they include detailed roofing or multiple glass sides.

Location

Your postcode can greatly affect what you’ll pay for conservatory cleaning. For instance, higher labour costs and demand can push prices up in big cities like London, Birmingham, or Manchester compared to rural or regional areas. Some cleaning specialists may also factor in travel time, so if you’re in a remote location, that might nudge your quote higher too. 

Aside from the labour rates, you must also consider how the local environment can impact how often and how deeply your conservatory needs cleaning. Living near busy roads or in industrial areas often means dealing with more airborne dirt, dust, and pollution that settles quickly on glass. 

Coastal homes may also face extra build-up from sea salt, while leafy suburbs can deal with sap, bird droppings, and algae. All this can mean a more frequent cleaning or extra effort to get it spotless again.

Meanwhile, Wales is one of the cheapest places to maintain a conservatory, but the cost can also easily go up to £500 during the rainy and winter months. It is, after all, one of the wettest UK regions, where mould and algae thrive better.

Conservatory cleaning prices also vary depending on the services you are looking for. Usually, conservatory cleaning specialists charge you based on the specific areas or elements you want them to work on.

This explains why you might get separate quotes if you like roof and gutter cleaning versus roof only. The same goes for interior and exterior cleaning, as well as wiping glass panels on windows.

A growing number, though, now offer full valet service. This is basically comprehensive conservatory cleaning inside and outside:

• External cleaning from top to bottom, including the roof, gutters, windows, doors, and frames

• Interior cleaning service from top to bottom, including the furniture, floors, walls and fabric blinds, and ceilings

• Deep cleaning and polishing of all surfaces

• Water-repellent treatment to protect the structure from the elements and make it easier to clean in the future

• Cleaning and lubricating door handles, locks, and hinges

• Restoration of conservatory furniture to prolong its lifespan

• Protection for conservatory plants

Others specialise in other maintenance and repair jobs and mainly extend such services to conservatories. A good example is a roofing expert who also tackles conservatory roof replacement.

Cleaning complexity

The more complex the job, the more time, tools and expertise it takes, which can increase the overall cost. For example, conservatories with high-pitched roofs or tricky angles often require ladders, safety equipment or specialist access tools. Heavy build-up like algae, mould or grime can also raise the price if your conservatory hasn’t been cleaned in a while.

Interior cleans can be just as detailed. Delicate conservatory blinds, built-in furniture or hard-to-reach corners all demand extra care. Some cleaners may also charge more for removing hard water stains or etched glass marks. If you want a streak-free finish on every panel, especially with floor-to-ceiling glass, it’s worth investing in a handyman with the right tools and experience to get the job done right.

How to save money on conservatory cleaning

Professional conservatory cleaning requires a budget. These tips help you save money whether doing it DIY or hiring a specialist:

• Use your own equipment. Buying basic cleaning equipment and supplies like a pressure washer, sponges, buckets, and solutions is cheaper in the long term, especially if you like to do regular cleaning.

• Clean regularly. Don’t let grime and dirt accumulate. Frequent light cleanings are easier and cheaper than infrequent deep cleans.

• Clean the outside and inside. Schedule time to thoroughly clean both the exterior and interior. Pay special attention to cleaning interior frames and sills, which can collect dust and dirt over time. Use a mild soap and water solution with a soft cloth to gently clean white frames and doors to prevent scratching them.

• Schedule seasonal deep cleans. Consider a professional deep-cleaning service once a year or every six months, depending on the conservatory’s condition.

• Compare offers. If you want to hire a cleaner, shop around. Get at least three to five quotes.

• Book ahead. Most conservatories would require cleaning after the winter, so schedule your cleaning project at least three months before.
